Investigating the risk of lightning’s pressure blast wave

Abstract: We investigated the pathology of human trauma associated with lightning's pressure blast wave. Within what range is a human at risk and what are the risks? Two theories for the trauma currently exist: the flash moisture vaporisation theory and the sixth mechanism theory. We performed a simple proof-of-concept experiment in a high-voltage laboratory to determine which theory makes for better predictions. The experiment confirmed the existence of a non-discriminant pressure blast wave around a spark in air. The … Show more

“…However, considering the five common electrical mechanisms of injury is the most useful for prevention and lightning safety education [5,45]. To complicate further, these can be combined, and blunt or concussive trauma/barotrauma may be overlaid on any of the five [5,45,68]. Figure 7 shows the relative distribution of these mechanisms in developed countries.…”
